Hi @Vallejo, Carlos
I noticed this issue in Service Health at Microsoft 365 admin center. It is a code conflict during meeting creation and update that causes incorrect time zone data handling for some meetings. The engineering team is currently deploying patches and performing validation, so please wait for the next update.
Title: Some users may see some meetings scheduled in Mexico time zones are displaying with the incorrect time.

Please confirm that users' devices are fully patched and up-to-date. For on-premises organizations, please also confirm your servers are fully patched and up-to-date.
For an immediate fix for reoccurring meetings created on or before April 1, 2023, that also had an instance of this meeting modified after this date, meeting organizers can make any small update, such as editing the subject or body, and save the change.
